The further object, of this invention is to provide apolishing machine capable of'a v j wide range of adjustment; so that-the. polishin'g means may be adapted to variously sized 1 plates 'of glass to polish the bevels (if-same.-

llowered operative position, that is, with its polishing wheels resting upon the "beveled" able means, thus moving glass plate to-back -.and' fbrth under the polishing-wheels, this I movement together with'that of the; polishing wheels constituting the-polishing opera;- V

when the said head 27 is raised entirely from a the operative position by lever 26' said.

wheels 36 will fall to a -lower position' as shown at the right in Fig. 1. 'Topolish beqels, that are'spac'e'd wider apart the polishing wheels may be moved apart upon fthei'r arboi's the desired distance, 'and-s'e cured. in, this position. To obtain a still greater distance between-two outer polish} ing wheels the adjacent .or ,inner Wheels of;

both sets of polishing means would be rey moved, and the frame l2- 12 would be adjusted. through hand-wheel 19 to obtain the required distance between the two outer polishing wheels. lVhenpolishing both bevels With the same device it is desirous to polish also the flat face of glass intermediate said bevels, and such operation is warranted by the provision of the face polisher 39 located at one side and intermediate the two bevel polishing Wheels, such location allowing the polisher 39 to over-reach the bevel edges'of the glass and thus polish the entire flat surface of the glass. Certain polishing ingre- (the absorbed and worked" upon the glass by the ffelt faced polishing wheels; and it i's' de-f sirens to keep this polishing material a moist, theref'ore'the provision of the troughm-eans' for, supplying water vto the bevel wheels,

which" means conform .to the various. mov

applied to the glass to be.

able positionsof said wheels',bec'ause of their I linked oonstruction. If it should be desirous to polish only the bevel faces of the glass in one operation;

the polishing wl1eel;.39-, woulrl' be removed and the 'shaft'22 raised, disengaging its gear connection, and collar 25 adjusted .to said shaft-in 1ts,raised position.

It is evident thatthe-arboi's- 35 might be lengthened and thus be eapable of polishing the bevels of'glass .of more varied width 'with'out resorting to the combination ofthe two polishing devices as,'w,as "above described;
